Excited electron

Vedclass · Answer

(B) An excited nucleus can emit $\gamma$-radiation when it transitions to a lower energy state,as the energy difference between nuclear levels is of the order of $MeV$.An excited electron,when transitioning to a lower energy state,emits electromagnetic radiation (such as visible light or $UV$) with energy typically on the order of $eV$.Since the energy associated with electronic transitions $(eV)$ is significantly smaller than the energy required for $\gamma$-ray emission $(MeV)$,an excited electron cannot emit $\gamma$-radiation.

Which one of the following cannot emit $\gamma$-radiation and why? $(i)$ Excited nucleus,(ii) Excited electron.
